    Abstract: Transmitting filesystem changes over a network is disclosed. A hash of data comprising a chunk of directory elements comprising one or more consecutive directory elements in a set of elements sorted in a canonical order is computed at a client system. One or more directory elements comprising the chunk are sent to a remote server in the event it is determined based at least in part on the computed hash that corresponding directory elements as stored on the remote server are not identical to the directory elements comprising the chunk as stored on the client system.

    Abstract: A system for storing data includes a performance storage unit, a performance storage transfer manager, a segment storage system, and a performance segment storage unit. The performance storage unit is for storing a data stream or a data block in. The data stream or the data block includes one or more data items. The performance storage transfer manager manages a transfer of the one or more data items to be automatically stored in the segment storage system over a network. The segment storage system is for storing a stored data item of the one or more data items as a set of segments. The performance segment storage unit is for storing the set of segments in the event that the stored data item has been stored using the segment storage system.

    Abstract: A system for processing data comprises a deduplicating system, an interface, and a processor. The deduplicating system stores a copy of data stored in a data storage system by storing a set of segments that is able to reconstruct the data stored in the data storage system. The interface receives an indication to revert data stored in the data storage system to a state of data at a snapshot time stored in the deduplicating system. The processor is configured to determine a subset of the data stored in the data storage system that has changed between the data stored in the data storage system and the state of data at the snapshot time stored in the deduplicating system using a first list of fingerprints associated with the data stored on the data storage system and a second list of fingerprints associated with the state of data at the snapshot time stored in the deduplicating system.

    Abstract: A system for storing data comprises a performance storage system for storing one or more data items. A data item of the one or more data items comprises a data file or a data block. The system further comprises a segment storage system for storing a snapshot of a stored data item of the one or more data items in the performance storage system. The taking of the snapshot of the stored data item enables recall of the stored data item as stored at a time of the snapshot. At least one newly stored segment is stored as a reference to a previously stored segment.

    Abstract: Cluster storage comprises an interface and a processor. The interface is to send a tag to a selected node and receive tags from the selected node. The tags received from the selected node comprise tags for likely similar segments stored on the selected node. The processor is to break a segment into subsegments, calculate subsegment tags for each subsegment, identify one or more references to one or more previously stored subsegments and/or one or more segment data using the tags from the selected node and the subsegment tags, and send the one or more references to the one or more previously stored subsegments and/or segment data and associated tags to the selected node.

    Abstract: A system for storing files comprises a processor and a memory. The processor is configured to break a file into one or more segments; store the one or more segments in a first storage unit; and add metadata to the first storage unit so that the file can be accessed independent of a second storage unit, wherein a single namespace enables access for files stored in the first storage unit and the second storage unit. The memory is coupled to the processor and configured to provide the processor with instructions.
